What series do you think kept their quality all the way through?

[The Cool Thatguy]

We all have shows that we love, even though they are less than perfect.

Sons of Anarchy, I love, but it did go on a little too long. The same of Burn Notice.

But some shows kept their quality, from beginning to end.

For me, it was Person of Interest and Strikeback.

The quality on them may have dipped at certain points, but were still great watches and rewatches.

What are some shows you thought kept their quality?

The Mandalorian
S.W.A.T
Chicago P.D
Reacher
N.C.I.S (any one)

Avatar: The Last Airbender - stands out to em because it was one of the series smart enough to pace itself out early on, so it really only increased in quality overall, and not only is there only *one* filler episode, but the show knew how to properly mock it.

The Mandalorian
S.W.A.T
Chicago P.D
Reacher
N.C.I.S (any one)

I was thinking along the line of series that have ended, not that are ongoing

[Mark Trail]

The Shield
TNG after the first season
Mary Tyler Moore
Mad Men
King of the Hill

Leverage comes to mind.

Bob's Burgers

You're the Worst

My choices are generally from the days of episodic television when it was a lot easier to maintain the quality they started with.

The Jeffersons (Strangely, was a spinoff from "All in the Family" but maintained itself better, mostly due to AinF losing half their cast in the last season).

The Wild Wild West

The Six Million Dollar Man

The Bionic Woman

Magnum, P.I.

I could go on and on.

Far more recent shows:

The Mandalorian

Lost in Space (Netflix version)

Star Trek Continues

I grant you, it's far easier to maintain quality when a season is ten episodes or so and sometimes more than a year apart.

Firefly
Green Lantern: The Animated Series

[Kirby101]

Breaking Bad is first show I thought of.

[K7P5V]

Definitely, my choice would be...

X-Men: Evolution

[Timothy Hunter]

Very few shows retain the same level of quality from the first season to the last. Most either gradually get better or worse.

Big Bang Theory. It was just as funny at the end as it was at the beginning.

30 Rock. I've been watching reruns and it was solid throughout.

Futurama was pretty consistent.

Setting aside the incredibly disappointing degree to which it left the source material behind?

Preacher

It was straight up "C Minus..." garbage for each of it's seasons.

Big Bang Theory. It was just as funny at the end as it was at the beginning.

That is to say, not very.

30 Rock. I've been watching reruns and it was solid throughout.

I'm inclined to agree, though I think the "Jack's wife in N Korea" arc came close to scuttling the last season.

Futurama was pretty consistent.

I'm not going to lie: After "Jurassic Bark," I never watched another episode. It upset me just that much. I'm talking "Old Yeller" levels of trauma so that I just can't watch a single episode of that show again without getting depressed.
